-FLUSH-TANK new. p

This invention relates to valves iniflush-w tanks, and more particularlyto rubber balls, very commonly used for closing such valves, and alsorelates to the connecting means for such balls."

One object of this invention is to save rubber and still have the sameclosing surface.

Another object is to provide simple con necting means for such valves.

Another object is to make the valves easily exchangeable, the rubbereasily engaging and disengaging in relation to my improved connectingmeans.

Another object is to make such valves more inexpensive, while retainingthe advantages of rubber balls.

Other objects will appear from the following description andthe appendedclaims as well as from the accompanying drawing,

in which--- Figure 1 is a vertical midsectional view of my improveddevice, illustrating a nearly or practically semi-globular part,preferably made of rubber, or similar material,

and my suitably shaped caps, made of sheet metal or similar materialcheaper than rubber, easily to be attached to such rubber part. V

Fig. 2 is a similar view, illustrating a slight modification of theinterengaging means between the semi-globular part and the cap.

Fig. 3 is another similar view, illustrating a still more slightlymodified form ofinterengaging.

In Fig. 1, 4 designates a nearly semiglobular body preferably made ofrubber or any other similar soft material easily seat ing itself intoavalve seat such as in flushtanks. The edge 5 of this body is providedwith re-inforcements or beads 6 and 7 forming the engaging means of thebody. These beads or engaging means may easily be of slightly differentform, without departing from the principle of the invention, as willeasily be understood. In Fig. 2, these beads are p actically e same inehough.

understoodgfrom the description later l on. In Fig. 8,.the inner head 8is slightly heavier thanthe head 6 ofFig. 1, so as to form a ratherstrong and littleresilient edgelO on the body 4, while the outer head 9,inthis figure 1s forming a thread-like surface, to

Qbe screwedtintorthevcap lll .Theycap 12,in Fig.1; 1s provided with anoutwardly rojecting rim 13, to engage with the body be ow thebeadi 6,from the inside of thebody, the body being slipped over the rim 13since, in this construction, the body is of rather soft material. Thesecond cap 14 is provided with the rim 15 toengage over bead 7 on thebody,

so as to form a water-tight interconnection between the caps and thebody. This device forms then my improved valve-ball, the bar 17 beingthe usual operating rod in flushtank-valves, as will easily beunderstood, without being illustrated in connection with suchflush-tanks.

In Fig. 2, the cap 19 is provided with the slightly inwardly curved rim20, forming the recess 23, into which the body 4: with the insertedspring 21 mayeasily be sprung, as will easily be understood. The spring21 is preferably a split steel-ring, split as indicated at 22, so as togive enough when ressing the soft body 4 to be sprung into t e recess 23of the cap 19. i l

Both modified forms of inter-engaging as illustrated in Figs. 2 and 3,form just as well as the inter-engaging means illustrated in Fig. 1 awater-tight connection between the body and cap as the device asdescribed in relation to the inter-engaging means in Fig. 1, as willeasily be understood, and other slightly modified forms may very easilybe devised without departing from the principle of the invention.
